4. 2. Nerve diffusion tensor imaging

   Author : Mikael Skorpil; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that in vivo visualises random translational movement of water molecules. DTI has inherent difficulties with low signal-to-noise ratio, sensitivity to patient motion, field inhomogeneities and fast T2 relaxation. READ MORE

5. 3. Fast Dynamic Processes in Solution Studied by NMR Spectroscopy

   Author : Mária Šoltésová; Jozef Kowalewski; Jan Lang; Gyula Batta; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear magnetic resonance; Dynamics; Ethanol; Cryptophanes; Saccharides; Nukleární magnetická rezonance; dynamika; ethanol; kryptofan; sacharidy; fysikalisk kemi; Physical Chemistry;

   Abstract : Nuclear magnetic resonance (NMR) spectroscopy is capable to deliver a detailed information about the dynamics on molecular level in a wide range of time scales, especially if accompanied by suitably chosen theoretical tools. In this work, we employed a set of high-resolution NMR techniques to investigate dynamics processes in several weakly interacting molecular systems in solution. READ MORE

6. 4. Applications of statistical methods in quantitative magnetic resonance imaging

   Author : Patrik Brynolfsson; Anders Garpebring; Tufve Nyholm; Eirik Malinen; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quantitative imaging; tumor imaging; dynamic contrast-enhanced MRI; diffusion weighted MRI; texture analysis; radiofysik; radiation physics;

   Abstract : Magnetic resonance imaging, MRI, offers a vast range of imaging methods that can be employed in the characterization of tumors. MRI is generally used in a qualitative way, where radiologists interpret the images for e.g. diagnosis, follow ups, or assessment of treatment response. READ MORE

7. 5. Dynamics of Fast Ions in Tokamaks

   Author : Per Helander; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Fast ions play a prominent role in the heating of tokamak plasmas by, e.g., neutral- beam injection, ion-cyclotron-resonance heating, and alpha-particle heating. In this thesis, a number of physical and mathematical problems concerning the dynamics of fast ions in tokamaks are addressed. READ MORE
